Just an idea to include in your letter:
MLK said that people should be judged not by the color of their skin but rather the content of their character.
The SA has chosen to judge people by the color of their skin.
That is racism.
Anti-white racism is racism.
They can deny it all they want, but the truth is out there now.
SA needs to denounce racism against white people, denounce any programs that support anti-white racism (like “Affirmative Action”) and insist that every person is treated the same regardless of the color of their skin.
Believe it or not, I included all of your points in my letter, which is on its way to the mail box.
